STTARY APPLIANCE FOR TELEPHONE-TRANSMITTJERS, 8w.

Specification of Letters Patent.

Patented July e, ltmtl,

Application filed December 10, 1919. Serial No. 343,862.

To all whom it may concern:

Be it known that l, SYLVAN T. Bann, a citizen of the United States, anda resldentof the borough of Manhattan, city, county,

and State of New York, have invented certain new and useful Improvements111 Sam- 'tary Appliances for Telephone-Transmitmanner as to conservehealth and prevent contagion.

The invention consists in the specific construction, combinatiomandarrangement of parts described and claimed, whereby a simple, cheap, buteffective sanitary attachment for mouth pieces of the character designated is attained; all as hereinafter more fully set forth.

In the accompanying drawings,

Figure 1, is a perspective view showing my protector as applied to themouthpiece of a telephone transmitter;

Fig. 2, is a sectional elevation of the mouthpiece, broken away in part,also showing my sanitary attachment in sectional elevation;

Fig. 3, is a front elevation of my device, without the cartridge holder;

Fig. 4, is a perspective view of an antiseptic cartridge;

Fig. 5, is a section of the cartridge holder, taken upon plane of line-5, Fig. 6;

Fig. 6, is a front View of the cartridge holder.

M, represents the bell-shaped mouthpiece of'an ordinary telephonetransmitter T, to which my sanitary shield or protector S, is applied.

p The appliance S, consists essentially of a disk shaped cap plate 8,formed with a central socket recess 8, for the reception and support ofthe cartridge holder 71., and with an inturned peripheral flange s ,tofit over and embrace the annular rim m, of the mouthpiece M.

. The cap plate 8, may be formed of sheet metal, celluloid, or any othersuitable material; and its peripheral flange 8 may be formed with anannular bead 8 to reinforce and stifien said flange. The rim flange 8 isalso split transversely to form one or more tongues s, which may be bentinward to contact intimately with the peripheral surface of themouthpiece M, and thereby lock the shield S, in position on themouthplece M, and sustain it against accidental displacement. The capplate 8, is preferably formed with two of these lock tongues .9diametrically opposed to each other as related to said cap plate 8, soas to clasp the mouthpiece M, on opposite sides thereof, as shown moreparticularly in Fig. 2, of the drawings, although ll do not confinemyself to any particular number of lock tongues 8 in this respect.

The depression in the cap plate 8, which forms the socket s, for thereception of the cartridge holder 72,, is preferably positionedcentrally of the disk, as shown (although this is not absolutelyessential) so as to afford an annular exterior surface which is formedwith a series of apertures a, a, which, when the device is in positionon a mouthpiece as in Figs. 1 and 2, communicate directly with theinterior of said mouthpiece M as shown more particularly in Fig. 2,thereby admitting of the transmission of sound waves to the diaphragmwithin the transmitter T.

The bottom of the socket s, is also formed with apertures a, for a likereason, and also for admission of emanations from the antiseptic cartride 0, into the interior of the mouthpiece In like manner the face plateof the cartridge holder h, (which may also be formed of sheet metal,celluloid, or other suitable material), is formed with apertures a awhich admit air and sound waves, and also allow the escape of antisepticemanations.

The inturned rim flange h, of the cartridge holder h, fits snugly withinthe side walls of the socket s, of the cap plate .9; and T prefer toprovide a screw thread connection between these parts, so that thecartridge holder may be firmly and yet detachably secured in position inthe cap plate 8. To this end the side walls of the socket s, are femalescrew threaded as shown in Fig. 2,- and the flange of the holder h, iscorrespondingly male-screw threaded as at h", Figs. 2 and 5. The flangeof the cartridge holder 72,, is somewhat wider than the depth of thesocket s, so that when screwed home thereon the body plate of the holderh, will protrude-slightly beyond the outer surface of the cap plate 8,as shown in Figs. 1 and 2, thus exposing an edge of the holder, which ispreferably milled, serrated, or otherwise roughened, as indicated at h,to facilitate finger manipulation when it is desired to remove theholder h, from the socket s, for the purpose of substituting a freshcartridge 0, and then again screwing the holder h, into its normalposition in the said socket s. The cartride 0, may be of any suitable ordesired antiseptic composition of volatile character; and may containdisinfecting, deodorizing or germicidal matter, any or all, in suitableproportions to effect the sterilization of all the parts adjacentthereto, both internal and external, so as to prevent germ propagationand contagion.

In this'connection the provision for replacement of the antisepticcartridges is an important factor, and obviates the discarding of thewhole device after the deterioration of a cartridge.

Furthermore my sanitary mouthpiece protector is so simple, light, cheapand portable in character as to be available for extensive use as ameans of eliminating the danger incidental to the use of telephonesgenerally, either public, or private.

WVhat I claim as my invention and desire to secure by Letters Patent is,

designated, comprising a cap plate formed with a peripheral flange andlock tongue means for embracing the rim of a mouthpiece and withapertures communicating with the interior of the mouthpiece when thedevice is positioned thereon, and also with a socket having an aperturedbottom, an apertured cartridge holder fitting in said socket in the capplate, and an antiseptic cartridge positioned in said holder, for thepurpose described.

3. A sanitary appliance of the character designated, comprising a capplate formed with a peripheral flange adapted to embrace the rim of amouthpiece and with apertures communicating with the interior of the-mouthpiece when the device is positioned thereon, and also with asocket having female threaded side walls and an apertured bottom, anapertured cartridge holder having a male threaded flange fitting in saidfemale threaded socket in the cap plate, and an antiseptic cartridgepositioned in said holder, for the purpose described.

4. A sanitary appliance of the character designated, comprising a capplate formed with a peripheral flange adapted to embrace the rim of amouthpiece and with apertures communicating with the interior of themouthpiece when the device is positioned thereon, and also with a sockethaving female thread-ed side walls and an apertured bottom, an aperturedcartridge holder having a male threaded flange fitting in said femalethreaded socket in the cap plate, said male threaded flange of theholder being also roughened externally to facilitate manipulation, andan antiseptic cartridge positioned in said holder, for the purposedescribed.

5. A sanitary appliance of the character designated, comprising a capplate formed with a peripheral flange and lock tongue means forembracing the rim of a mouthpiece, and with apertures connecting withthe interior of the mouthpiece when the device is positioned thereon,and also with a socket having female threaded side walls and anapertured bottom, an apertured cartridge holder having a male threadedflange fitting in said female threaded socket in the cap plate, and anantiseptic cartridge positioned in said holder, for the purposedescribed.

6. A sanitary appliance of the character designated, comprising a capplate formed with a peripheral flange adapted to embrace the rim of amouthpiece and with apertures communicating with the interior of themouthpiece when the device is positioned thereon, and also with a sockethaving an apertured bottom, and an antiseptic cartridge positioned insaid cap plate socket, for the purpose described.
